Configuring a network with 4.2BSD and 4.3BSD VAXen.

[Steve Herber]

I have a LAN with VAX 780 4.3BSD and VAX 785 4.2BSD systems on it.  I have
just installed the 4.3BSD release on the 780 and I am having a problem
getting all of the networking goodies working.  I am able to do the usual
things (rlogin, rsh, rcp) but I cannot get sendmail to work from 4.3BSD to
4.2BSD and the rwhod daemon willnot send information from the 4.3BSD system
to the 4.2BSD.  In both of these cases, everything works going from 4.2BSD
to 4.3BSD.  I have a feeling that if is a problem with the way the 4.3BSD
system now sends out broadcast messages.  I have tried a number of combinations
of 'ifconfig netmask' and 'route add/delete' commands without success.

I am enclosing portions of my configuration files for your consideration.
(Gee, and I always thought I could rtfm well enough).

/etc/hosts
127.1		localhost local
27.1		bgsu-stu student s   <== 4.3BSD
27.2		bgsuvax research r   <== 4.2BSD

/etc/networks
loopback-net	127		software-loopback-net
bgsu		27		BGSU net

/etc/rc.local
hostname bgsu-stu
ifconfig lo0 localhost
ifconfig il0 `hostname`
hostid `hostname`
route add net bgsu `hostname` 0
route add net loopback-net localhost 0

Just a quick look at the current configuration.....

One last thing.  I have turned on the 4.2BSD Compatibility options in the
kernel, COMPAT_42 and TCP_COMPAT_42.  Thanks in advance for the help.

Isn't it fun to learn everything about everything???
